I

1., An airline oiler comprising a casing constituting anoil reservoir, tubes in the casing for conducting pressure fluid. through the reservoir, and fabric members in the reservoir including circular bodies for conducting oil from the reservoir to the tubes, saidbodies being disposed transversely of the casing to divide the same into separate chambers and having grooves in their peripheries to permit oil to pass to opposite sides of the bodies.

or scope between said air line and said reservoir, and j'ca'pllla ry means in" said passage arranged to con-tacttheoil in said reservoir irrespective of the position thereof or the quantity of oil therein, said means effective to divide said reservoir into a plurality of chambers.

"7. An air line oiler including a pair of sections adapted 'to be 'detachably secured together, each section including a tube adapt- "ed to be associated with an. air .conduit, and

capillary means adapted to be clamped between said tubes when'said sections are secured together.

8. An air line oiler including an oil reserv oir, an air conduit associated therewith, and capillary means positioned in said reservoir and communicating with said air conduit and substantially every portion of the inner surface ofsaid reservoir,,whereby said capillary. means conducts oil from said reservoir to sai'dconduit irrespective of the position of said reservoir or the quantity of oil therein. 7

9. An air line oiler including an oil reservoir, an air'con'duit associated therewith, and a fabric body communi cating with said air conduit, and disposed in said reservoir in such a manner as to divide the same into separate chambers, and a passage through said body permitting oil to passfrom one to another of said chambers.

10. An air line oiler including an air conduit,;an oi-l reservoir comprising a plurality of chambers, an'd' a fabric body communicating withvsaitl conduit; and said reservoir, said body being arranged insuch a manner that a portion thereof serves ashan air passage to conduct air pressure pulsations from said conduit to said reservoi-r,and another portion thereof, serves as an oil passage to conduct oil from the reservoir into the conduit.
